SPEGIFIGATION forming part of Letters Patent No. 490,571, dated January 24, 1893.

Application filed October 24, 1892. Serial No. 449,831. (No model.) Patented in Switzerland July 2, 1890, No. 2,436: in Germany July 11, 1890, No. 60,148; in England July 23, 1890, No. 11,543: in France July 25, 1890, No 207,215; in Belgium August 20. 1890, No- 91,678, and in Austria-Hungary November 13, 1890, No. 3,314 and No. 3,278.

To all whom it may concern.-

Be it known that I, ALOYS MARIA LEIN- WATHER, a subject of the Emperor of Austria- Hungary, and a resident of the city of Basie, Switzerland, have invented certain new and useful Improvements in Car Wheels, (for which I have obtained patents as follows: in

Switzerland, No. 2,436, dated July 2, 1890; in Germany, No. 60,143, dated July 11, 1890; in France, No. 207,215, dated July 25, 1890; in England, No. 11,543, dated July 23, 1890; in Austria-Hungary, No. 3,314 and No. 3,278, dated November 13, 1890, and in Belgium, No. 91,678, dated August 20, 1890,) of which the following is a specification.

This invention relates to spherical carwheels to be used on railways the rails of which have a number of longitudinal corrugations or ridges.

With reference to the accompanying drawings: Figure 1 is a vertical section on line 1, 1 Figs. 3 and 4, Fig. 2 a front view, Fig. 3 a side elevation and Fig. 4 a plan of the improved ball wheel. Fig. 5 shows in vertical section the guard O hereinafter referred to.

The improved spherical wheel consists of a hollow or solid ball or sphere A designed to run on the longitudinally corrugated rails B. A guard C has journaled in its downwardly projecting arms two guide rollers D shaped like bobbins or spools and kept in close contact with the ball at its lower front and rear parts as clearly shown in Figs. 2 and 3. The top of this guard 0 forms the bearing of a pivot plate E resting against the top of the ball, antifriction balls F being interposed between the top of the guard L and the pivot plate E in order to diminish friction. These balls F are separated from each other by a disk II provided with circular holes to re- The form and position of ceive the balls F.

the pivot plate E are substantially those shown in the drawings.

The guard C is held in position by the bracket G secured to the car frame and having ribs entering into vertical grooves I at the side of the vertical arms of the guard.

The weight of the car is transmitted to the guard O by means of spiral springs K which bear against the underside of washers on bolts Lou the top of which the car frame rests-aud against the topof brackets on the downwardly projecting arms of the guard O.

The guards O of two corresponding wheels at opposite sides of the car are held connected by gage rods M secured to such guards.

When the car is drawn forward the ball A and the pivot plate E revolve as indicated by arrows in Fig. 3.

I claim 1. The combination of the spherical wheel or ball A with the guard 0 provided with downwardly projecting arms and guiding rollers D journaled in said arms in contact with said ball, substantially as and for the purposes described.

2. The combination of spherical wheel A, guard C and guiding rollers D, with longitudinally corrugated rails B, substantially as described.

3. The combination of spherical wheel A, guard C, pivot plate E and antifriction balls F, substantially as described.

4. The combination of spherical wheel A, guard C, spiral springs K and bolts L.

In testimony whereof I have affixed my signature in presence of two witnesses.
